Water Absorption Characteristics of Two Rattan Species (Laccosperma Secundiflorum and Eremospatha Macrocarpa) from Fresh Water Swamp, Lagos State and Rain Forest, Edo State, Nigeria

Abstract

Water Absorption is one of the properties that determine the suitability of rattan canes as structural material especially for outdoor use. This study therefore evaluated the water absorption characteristics of two rattan species (laccosperma secundiflorum and eremospatha macrocarpa) from a fresh water swamp, Arapagi village, Lagos state and rain forest-Nicholas village, Edo state in Nigeria by collecting three matured wild rattan species from each ecological location and the water absorption carried out after 24 hours and 48 hours respectively. The results show that, water absorption after 24 hours ranged from 39.63 % to 82.51%. However, water absorption after 48hours increased from 44.53 % to 93.74 %. It was also observed that water absorption after 24 hours and 48 hours increased along the axial direction from base to top. Meanwhile, the samples of the two rattan species sourced from Rain forest had lower water absorption values than Fresh water swamp. In conclusion, the two rattan species had different levels of water affinity, however, samples obtained at the base from Rain forest absorbed less water.
